Boss Protocol

A Boss Protocol monster has a special flag set. Some monsters and all MVPs have this flag set. They have the following attributes:

• Various skills fail them;
  • Mental Sensing
  • Steal
  • Intimidate
  • Classical Pluck will not stop them from casting spells.
  • Provoke
• The knockback aspect of skills does not affect them.
• They detect the Hiding status and any other skill statuses that is similar to it.
• The time Ankle Snare holds them is reduced.
• Unaffected by status effects;
  • They cannot be silenced, stunned, poisoned, etc.
  • Exception: Slash can inflict a coma on all undead monsters, including bosses. Otherwise, even coma from Tarot Card will not work on monsters with the boss protocol.
• Affected by all items geared towards "bosses," i.e.;
  • Abysmal Knight Cards increase damage to them by 25%
  • Alice Cards reduce damage dealt by them by 40%

Example for common monsters with Boss protocol:

• Monsters of Thanatos Tower Lv.7 and above
• Owl Duke
• Owl Baron
• Kasa and Guardians in Thor's Volcano
• The level 99 Biolab monsters

Mini-Boss

Mini-Bosses do not actually exist: this is a player-coined term to describe a rare monster, considered as such because they have set spawn intervals ranging from as quick as 10 minutes to as long as 2 hours, unlike normal monsters that spawn instantaneously. Similar to an MVP but not quite exactly like, Mini Bosses are usually programmed under a Boss protocol, with some even being able to summon mobs. Just like MVPs, these monsters are no longer FFA.

Monsters that people tend to classify as Mini-Bosses are:

• Angeling
• Any * of Thanatos monsters besides Memory of Thanatos
• Arc Angeling
• Cat O' Nine Tails
• Chimera
• Dark Illusion
• Deviling
• Dragon Fly
• Eclipse
• Executioner
• Gemini-S58
• Ghostring
• Gryphon
• Hellion Revenant
• Hydrolancer
• Mastering
• Maya Purple
• Mutant Dragonoid
• Mysteltainn
• Ogretooth (Also known as Tirfing)
• Toad
• Ungoliant
• Vagabond Wolf
• Vocal
• Zealotus
